中文摘要:

      通过遥感图像处理与目视解译,对扎布耶盐湖典型矿床从控矿构造、矿物质来源、湖盆封闭性和沉降性、地形地貌、水热活动、遥感色异常及退宿湖痕迹等因素进行了总结,初步建立主要盐类矿产资源的遥感找矿模式。经过综合分析,对比扎布耶盐湖典型矿床的成矿地质条件,以近矿找矿标志及遥感成矿信息为依据圈定了24个成矿条件优越、遥感找矿标志明显的区域为钾盐矿最小预测区。该研究可为矿产潜力评价及以后的工作奠定基础。

英文摘要:

      Remote sensing technology can make up some defects of the traditional method,limited by natural geographical condition in Tibet Aatonomews Region salt lake research.This paper has preliminary established main salts mineral resource prospecting model based on remote sensing through analyzed some factors about Zabuye typical ore deposits by image processing and visual interpreting.And these factors involved Ore- control structures,mineral sources,semi- deep- lake closure property and setteabihty,topography,hydrothermal activity,color anomalies and the trace of vanished lake as well.After comprehensive analysis and contrast the ore-forming geological conditions of Zabuye salt lake,24 potassium mineral minimum forecasting areas have been delineated at some superior metallogenic condition and obvious remote sensing ore- prospecting regions.The research would lay good foundation for mineral potential evaluation and later work.
